In my experience, they are able to connect you with people who should be able to resolve your problem. Sort of like sending you directly to an operator. I was able to solve a problem with my YouTube Premium/Google Music subscription using it in about 20 minutes. My problem was I have an account from beta Google Music that has been grandfathered for years and I lost YouTube ad free when they recently restricted it. They forwarded me to someone at YouTube who actually was able to resolve it.
